We’re still waiting on some official gameplay videos from publisher Activision and developer Terminal Reality for The Walking Dead: Survival Instinct, but if you want to pre-order the game without seeing it in action, GameStop will be giving you some exclusive DLC and a Walker Ear keychain (no picture, unfortunately).

I've seen one clip of gameplay that was actual footage from the game and it's been on a commercial during every episode of The Walking Dead. It was like 5 seconds haha. It's weird that the game releases in just over 2 months and we've seen nothing.
